Hi Ron,


Before I start, I would like to say that you should have post this
message on an exchange newsgroup rather than this newsgroup.

Having said that, here is some information:


First of all, the M drive is a virtual drive. There is no fixed size on
it, so it will grow or shrink whenever needed.

If you open the exchange manager, expand administrative groups --> first
admin. Gr. --> servers --> <your server name> --> First storage group
--> right-click on mailbox store 1 --> properties --> database tab......
here you will find the location of your exchange database that actually
stores all the mail...OK, now you know the drive it is on....Does it
have enough disk space????

And if you have multiple stores, check them as well.


More important (or: Most important) : Be sure not to backup the M
drive!!! This will cause severe problems. By backing up the exchange
database, you have everything you need. The M drive is just a viewable
version of that database.


Looking at the error that you added to the message:

It looks like the "exchange domain servers" group can no longer be
found. I hope it's not deleted.

Alls exchange servers are a member of this group, and I wouldn't know
what would happen when it's removed......but I don't think it's a good



My 2 eurocents....

Subject: [windows2000] M Drive full


For some reason the M drive on our Exchange2000 server is completely
full.  We are doing backups which are set to flush the logs.  I have
asked all users to delete anything they can to clean up.  


The application log is full of these error messages:



Microsoft Exchange System Attendant failed to read the membership of
group 'cn=Exchange Domain Servers,cn=Users,dc=MyDomain,dc=lan'. Error
code '80072030'. Please check whether the local computer is a member of
the group. If it is not, stop all the Microsoft Exchange services, add
the local computer into the group manually and restart all the services.

The MAPI call 'OpenMsgStore' failed with the following error: 

The attempt to log on to the Microsoft Exchange Server computer has
failed.  The MAPI provider failed. Microsoft Exchange Server Information
Store ID no: 8004011d-0512-00000000


I believe that if I can somehow get the M drive cleaned up then these
errors will go away.

Any ideas?    TIA.
